Lawn MOWER.

Application filed November 12, 1924. Serial lid-749,511.

This invention relates to improvements in lawn mowers and has for an ob ect the I'OVlSlOIl of a motor erated mower which is of light and dura le' construction and Another object of the invention is the provision of a lawn mower which includes 15 suction means for gathering the cut grass and for directing t e cut grass into a bag or suitable container.

A further object of the invention is the provision of a lawn mower in which a motor is utilized for operating both the cutter and the suction means. With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings 1-- constructed in accordance with the invention.

Figure 2 is a top view of the same. Figure 3 is a central vertical section with the motor housing in elevation.

Figure 4 is an enlarged fragmentary sec- F tion on the line 4- -4: of Figure 3. Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the improved mower as shown comprises a housing which includes a substantially central fan chamber 10, upon the top of which is mounted a motor chamber 11 w i or beneath the fan chamber is a suction chamber 12. This suction chamber is open at each end and its inner end communicates with the fan chamber while its outer end is provided with a relatively narrow laterally flared mouth 13. The fan chamber 10 has extending therefrom a tubular dis charge passage 14: which communicates with the interior of a bag or similar receptacle 15 which is designed to receive the cut grass, as will be hereinafter apparent.

The housing is mounted upon supporting wheels 16 which are secured to the said Figure lie 9. side elevation of a mower.

le extending from the opposite side and suction chambers, the last mentioned housing by bearing brackets 17 Q -Mounted upon the axle of the wheels 16 is the bifur-' cated end 18 of a handle 19,the lower ends of the handle being secured to the housing as indicated at 20. Secured along the mouth 13 of the suction chamber 12 by means of screws or bolts 21 is a stationary cutter bar 22 and mounted for sliding movement upon this bar is a mov able cutter bar 23, the latter having a screw and slot connection 24 with the bar 22 so that it may be horizontally reciprocated.

For the'purpose of operating the movable cutter bar 23, the latter has a pivotal connection 25 with one end of an oscillating lever 26, the said lever being pivotally mounted as shown at 27. The opposite end of this lever has a sliding pivotal connection as shown at 28 with one end of a crank arm 29, the latter being secured to the lower 7 end of the shaft 30 of a motor 31 which is -mounted within the motor chamber 11, The

shaft 30 is supported by a bearing 32.

The shaft 30 extends through the fan chamber 10 and the suction chamber 12 and secured upon this shaft within the chamber 10 is a fan 33, so that the motor in addition to operating the cutter at the outer end of the suction chamber also operates the fan.

By this means grass or other vegetation which is cut by the cutter will be drawn into and through the suction chamber 12 by the action of the fan 33 and will be discharged outward through the discharge passage 14 into the bag 15.

The cutter bar 10 may be supported by suitable runners 34 as is usual in devices of this character.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as proper-v ly fall within thescope of the appended claims. 1

Having described the invention what is claimed is 4 1. A lawn mower comprising a housing including a motor chamber, a suction cham-- her and a fan chamber between the motor chamber being open at both ends, a horizontal reciprocatory cutter at the outer open end of the suction chamber, a motor within the motor chamber and having its shaft extending through the fan chamber, a fan lono motor shaft, a discharge passage for thecated' within the fan chamber upon the fan chamber, a crank arm secured to the motor shaft and a pivotally mounted oscil lating lever having one end operatively connected to the crank arm and its opposite end operatively connected to the reciprocatory cutter whereby the latter ma be operated.-

2. A lawn mower comprislng a housing including-an upper motor chamber, an intermediate fan chamber located beneath and arranged axially of the motor chamber and a lower suction chamber, said suction cl1an1- her being open at both ends and having one of its ends in communication with the fan chamber approximately central of the latter, a motor within the mot? chamber and having its shaft extending ownwardly through the fan and suction chambers, a fan upon the shaft within the fan chamber, an outlet for the fan chamber, a cutter arranged at the outer, end of the suction chamber and means connecting the cutter and shaft to operate said cutter.

In testimony whereof We affix our signa- 25 tures. v
